[CA] [CA11] I40 wind question

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum RJ,

The Rotavecta wind transducer is typically recommended for powerboat applications rather than sailing applications. This recommendation is rooted in the inherently greater accuracy and ability to extend the wind vane transducer's cable. That said, the Rotavecta transducers are occasionally installed on sail boats where the performance / features of a wind vane transducer are not required.

With respect to the symptom reported, calibration of any wind transducer is required ... especially for Rotavecta transducers. Chapter 10.3: User calibration of the Chapter 4.3 ACU-100, ACU-150 connection of the i40 Instrument Installation and Operation Instructions details the actions required to properly calibrate the Rotavecta wind transducer. Has this calibration been performed?
